METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING CONTROL INFORMATION TO RANDOMIZE INTER-CELL INTERFERENCE IN A MOBILE COMMUNICATION SYSTEM

摘要

Methods and apparatuses are provided for transmitting and receiving information. A User Equipment (UE) identifies a sequence based on a Zadoff-Chu sequence and ejα, where a cyclic shift value α is defined per cell. The UE identifies information for an orthogonal sequence. The UE generates a signal by using the information, the sequence and the orthogonal sequence. The UE transmits the signal in a Single Carrier-Frequency Division Multiple Access (SC-FDMA) symbol to a Node B.

1. A method for transmitting information, the method comprising:
identifying, by a User Equipment (UE), a sequence based on a Zadoff-Chu sequence and ejα, where a cyclic shift value α is defined per cell; identifying, by the UE, information for an orthogonal sequence; generating, by the UE, a signal by using the information, the sequence and the orthogonal sequence; and transmitting, by the UE, the signal in a Single Carrier-Frequency Division Multiple Access (SC-FDMA) symbol to a Node B.
